Next takes is to the Next iteration, but End naturally does the same thing.
Example:
For each
'Do something
Next
End
For Each
'Do something
End
They are the same thing. Next is typically used when you are trying to skip the rest of the steps in the loop based on a conditional statement.
Ex.
For each
If %CurrentItem.Name% = John
Next
End (if)
'Do something (will only occur if %CurrentItem.Name% is not John)
End (for each)
Exit Loop cancels out a loop completely, so as I read it, you are telling it to only iterate once on the second loop, because you are telling it every time to exit this loop.
